Abstract
Embodiments of a method used for determination of inhibition durability index (IDI) of an inhibitive mud system can include multiple stages, with each stage including specific steps. The first stage can include a dispersion test that evaluates the inhibition effects of a stability inhibitor after exposing the test material to the inhibitor. The second stage can include a durability inhibition assessment, which includes assessing the longevity of the effect of the inhibitor. A third stage can be used to graph or otherwise evaluate the results of the second stage or the first and second stages.
